Here’s a day-by-day look at how Boston's AFL contingent is faring:
Oct. 21: Peoria 4, Scottsdale 3
Tanner Houck continued his run of buzzsawing opposing bats’ bats during the Fall League with his performance Monday against Scottsdale. Houck piled up six strikeouts while yielding just two hits and one run en route to earning the victory. His start was kept to four innings as he scuffled to find the zone at points, finishing with 38 of his 71 pitches going for strikes. He sat consistently in the 94-95 mph range with his fastball, displaying devastating offspeed stuff to complement. The 23-year-old right-hander recorded at least one strikeout in each inning of work.
Jarren Duran tagged a pair of singles out of the No. 2 spot in the batting order, raising his average to .256 in the process. He was caught stealing in the fifth, but he has collected six hits over his past five games. Brett Netzer was back in the lineup for Peoria and went 1-for-4 with three strikeouts while batting ninth. After he struck out and reached first by wild pitch in the fourth, he was involved in one of the game’s more bizarre plays as he was thrown out attempting to steal second on a 3-2 pitch that had a delayed strike three call due to the automated strike zone utilized at Salt River Fields. It was his first stolen base attempt of the fall.
Oct. 20: Mesa 8, Peoria 2
Yoan Aybar had a rough night on the mound as he gave up a pair of homers and surrendered four runs on three hits in his lone inning. Jhonathan Diaz had a brief appearance, but fared well. Diaz struck out one and threw three of four pitches for strikes in two-thirds of an inning. Jarren Duran has hits in three of his past four games and is finishing the AFL on a high note. The speedy outfielder swiped his fourth base and also scored a run as part of his 1-for-4 evening. C.J. Chatham went 0-for-3, but did pick up his ninth RBI via a sacrifice fly in the eighth. Brett Netzer went 0-for-3, but did draw a walk and score a run.
Oct. 19: Mesa 5, Peoria 1
Jarren Duran opened Peoria’s fourth inning with a triple but ran into the final out of the frame when he attempted to steal home with two outs on the catcher’s throw back to the pitcher. The triple was Duran’s second in the Fall League and marked the Javelinas’ only extra-base hit on Saturday. Brett Netzer is batting .231 after an 0-for-2 performance. Bryan Mata, one of the hardest throwers in this year’s Fall League, allowed two runs and five baserunners (2 H, 3 BB), but also ran his fastball up to 97 during an inning of relief for the Javelinas. The 20-year-old righty has worked exclusively out of ‘pen this fall, posting a 5.79 ERA with as many walks as strikeouts (nine) over 9 1/3 innings.
Oct. 18: Peoria 9, Salt River 0
C.J. Chatham plated a run with each of his two hits, as he delivered a run-scoring single in the second inning to put Peoria on the board before adding an RBI double in the eighth. The Red Sox No. 9 prospect finished the game 2-for-4, snapping a 1-for-20 skid at the plate, and overall he’s batting .250 with eight RBIs through 15 games. After going hitless in his first two games, Brett Netzer was stellar, notching three hits, including a fifth-inning RBI double for the Javelinas. Jarren Duran lifted a sac fly in the seventh inning, but he finished 0-for-4 to bring his AFL average to .246.
Oct. 17: Scheduled day off for all Arizona Fall League teams.
Oct. 16: Salt River 4, Peoria 2
Jarren Duran hit his fourth double of the fall in his two-hit day, raising his average to .262. The outfield prospect also drove in a run for Peoria in the bottom of the third. C.J. Chatham finished 0-for-4 as the Javelinas’ third baseman. Jhonathan Diaz allowed a run on three hits and a walk, and he struck out two batters in his two-inning appearance.
Oct. 15: Surprise 3, Peoria 0
Tanner Houck surrendered one run in five innings for a second straight start as he lowered his Fall League ERA to 2.79. The Red Sox's No. 5 prospect threw 50 of 79 pitches for strikes in the outing as he scattered three hits, issued one walk and struck out five. After two shaky starts at the outset of the AFL, Houck, a former first-round pick (2017), has racked up 17 strikeouts and allowed just two runs on 10 hits across his last 14 innings (three starts).
Jarren Durran went 0-for-4 from the leadoff spot, dropping his Fall League average to .246. C.J. Chatham, who followed Duran in Peoria’s lineup, is batting .250 after a 1-for-4 performance. His leadoff single in the fourth accounted for half of Peoria’s hits.
Oct. 14: Surprise 1, Peoria 0
Yoan Aybar had an eventful outing Monday, which began by yielding a leadoff homer. He would go on to plunk back-to-back hitters during the frame, before escaping further damage with his second strikeout. He sat consistently at 93-96 mph with his fastball, ending his outing on a 90-mph slider. Bryan Mata took over for him and had to work around action on the basepaths (including one passed ball and a wild pitch) before ultimately escaping without a run crossing the dish. The Red Sox's No. 3 prospect was consistently at 97 mph with his fastball, and after his two-strikeout outing Monday, has eight punchouts in six AFL outings. Both Jarren Duran and Brett Netzer went 0-for-4 for Peoria, with the duo combining for five strikeouts.

Oct. 11: Peoria 8, Glendale 3
Jarren Duran, Boston's No. 4 prospect, roped three hits during Peoria’s win, coming just a home run shy of hitting for the cycle. Voted as having the best speed of any prospect in Saturday’s Fall Stars Game, Duran put those wheels on display when he socked his first triple of the Fall League to right in the second. He capped his team’s win by clearing the bases with a two-RBI double over the center fielder’s head in the sixth. The 23-year-old also scored three runs while batting in the No. 2 slot. Marcus Wilson finished 1-for-4, but very nearly hit his second AFL blast in the sixth before a light breeze knocked down his drive to right. He owns an .879 OPS through his first seven games with the Javelinas.
Oct. 10: Glendale 5, Peoria 2
Jarren Duran, Boston’s No. 4 prospect, singled in a 1-for-4 day at the dish, while Brett Netzer went 0-for-3 with two strikeouts.

The Venezuelan southpaw has now accrued 12 punchouts across 6 2/3 frames with Peoria.
Oct. 9: Peoria 3, Scottsdale 1
C.J. Chatham’s struggles continued as he went 0-for-4 with a trio of strikeouts. Chatham is hitting .250 in Arizona, but is hitless (0-for-12) over his past three games. Marcus Wilson popped out in each of his first two at-bats, but finished the night strong with base hits in each of his final trips to the plate. Wilson, who had been hitless in 10 straight at-bats before those hits, is batting .346 through seven AFL games.
Oct. 8: Peoria 3, Scottsdale 2
Tanner Houck allowed one run on four hits over five innings against Scottsdale in his longest AFL start for the Javelinas. The Red Sox's No. 5 prospect struck out four but struggled with his control, as he issued three walks and hit one batter while throwing 43 of 82 pitches for strikes. Houck, Boston’s first-round pick from the 2017 Draft, showed impressive stuff in the outing, operating at 92-95 mph with a heavy fastball that helped him to induce nine ground-ball outs. He threw his hard, upper-80s/low-90s slider 36 times in the outing, generating seven whiffs, and also recorded three swinging strikes with his mid-80s changeup. Overall, the 23-year-old right-hander has compiled a 3.14 ERA in the Fall League, striking out 15 in 14 1/3 innings.

Left-hander Yoan Aybar struck out a pair of batters during a scoreless eighth inning as he lowered his Fall League ERA to 1.50. 20-year-old righty Bryan Mata had a shaky ninth, as he allowed one run on two hits and a walk, though he still managed to pick up his first AFL save while running his fastball up to 98 mph.

The Red Sox’s No. 5 prospect had allowed six runs, four earned, over his first two Fall League appearances. The club’s first-round Draft pick in 2017 spent this season at the Double-A and Triple-A levels and split his time between starting and coming out of the bullpen.

Duran started the season red-hot for Class A Advanced Salem, batting .387 in 199 at-bats for the Red Sox.

C.J. Chatham served as the designated hitter and finished 1-for-4 with a run, an RBI and a walk. His hit opened the scoring for Peoria, as he singled home Duran in the top of the first.

Lefty reliever Yoan Aybar (No. 29) came into the game with a runner on and two outs in the seventh inning and got out of the jam, then went on to retire the side in order in the eighth. He got all four outs via the ground ball. No. 3 prospect Bryan Mata made 21 starts across two levels in 2019, but he came in to finish things off in his AFL debut. Mata was throwing 97-99 mph with his fastball, though he struggled with his command and hit a batter. He did, however, put up a zero in the ninth.
Sept. 18: Peoria 10, Salt River 6
Red Sox hitters played a key part in Peoria erasing an early 5-0 deficit and going on to win, 10-6. Marcus Wilson went 3-for-4 with a double, a walk and three RBIs.
