Days after opting out of his Minor League contract with the Angels, Doug Fister is set to oppose them as he makes his 2017 Major League debut when Boston faces Los Angeles today at Fenway Park.
The Red Sox claimed Fister off release waivers from the Angels on Friday, and slated him as their starting pitcher for Sunday's series finale against his former club.
An eight-year big league veteran, Fister went 12-13 with a 4.64 ERA in 32 starts for the Astros last season, and owns a 3.60 career ERA. The 33-year-old hurler rejoins Red Sox general manager Dave Dombrowski, who acquired Fister in 2011 when Dombrowski was a member of the Tigers front office.
Fister's Red Sox journey begins versus Angels right-hander Parker Bridwell, who is 1-0 with a 3.07 ERA in three games (two starts) this season. First pitch is scheduled for 1:35 p.m. ET and willl stream live on MLB.TV.

Here's what else to watch for throughout the day (all times ET):
Stellar swingman: CHC@MIA, 1:10 p.m.
Cubs left-hander Mike Montgomery has been a starter and a reliever throughout his three-year career, and after appearing in 18 games out of Chicago's bullpen to begin 2017, he's been called on to start in his last three outings.

The 27-year-old has fared quite well, recording a 2.40 ERA in his starts while picking up his first win of the year his last time out as he held the Padres scoreless in six solid innings.
This afternoon Montgomery faces the Marlins and right-hander Edinson Volquez, who is looking to get back on track after back-to-back rough outings. Volquez, who threw the league's only no-hitter this season in his first June start, has allowed 10 earned runs over his last 8 2/3 frames.
Containing Edwin: MIN@CLE, 1:10 p.m.
One complete game shy of his career high of four, the Twins' Ervin Santana already has set a personal best for a single season with three shutouts. Since his most recent shutout June 9, however, he has allowed 11 earned runs in 10 innings.

In a matinee matchup versus the Indians, Santana will look to right the ship, but avoiding Edwin Encarnacion will be his toughest task. The Cleveland slugger has a double, three home runs and seven RBIs in 28 career at-bats against the Minnesota right-hander.
Cleveland right-hander Josh Tomlin, who is 4-8 with a 6.07 ERA, gets the ball in the series finale.
Seizing the rubber match: TEX@NYY, 2:05 p.m.
With the series tied at one apiece, the Rangers and Yankees enter the finale trying to secure a win in the weekend set. Right-hander Michael Pineda takes the mound for the Yanks as he attempts to get back in the win column after consecutive no-decisions against the Angels.

Rangers righty Nick Martinez toes the rubber opposite Pineda looking to extend his string of quality starts to three. Martinez earned a victory over the Blue Jays, allowing one run in 6 1/3 frames his last time out.
Wild West: COL@LAD, 4:10 p.m.
Two of the National League's best teams go head-to-head in a division clash when the Rockies and Dodgers square off in the series finale at Dodger Stadium.

Left-hander Tyler Anderson tossed a scoreless inning in his return from the disabled list earlier this week, and returns to the rotation after fully recovering from inflammation in his left knee. Anderson hasn't made a start since May 30, when he allowed six runs in five innings in a loss to the Mariners.
The Dodgers counter with right-hander Brandon McCarthy, who stymied the Mets with six scoreless innings in a 12-0 win on June 20.
Division battle in Seattle: HOU@SEA, 4:10 p.m.
No starting pitcher in baseball has induced a higher whiff-per-swing rate with their slider (53 percent) than the Astros' Brad Peacock, according to Statcast™. Peacock, a reliever to begin the year, has excelled since being inserted into the Houston rotation largely as a result of an improved slider.

The pitch has helped the 29-year-old strike out 35.7 percent of the batters he's faced this season, and he has held opponents to a .212 batting average through his six starts. Peacock tries to build on his impressive transformation when he toes the rubber versus the Mariners this afternoon.
Seattle counters with left-hander Ariel Miranda, who is 3-1 with a 2.20 ERA in seven home starts this season.
