The Texas Rangers today announced the following transactions, bringing the club's active roster to 33 players:

• Infielder Hanser Alberto (#2) activated from 10-day disabled list.
• Right-handed pitcher Austin Bibens-Dirkx (#56) recalled from Triple-A Round Rock.
• Outfielder Willie Calhoun (#5) recalled from Triple-A Round Rock.
• Right-handed pitcher Adrian Sampson (#52) contract purchased from Triple-A Round Rock.
•Left-handed pitcher C.D. Pelham (#64) contract purchased from Double-A Frisco.

Alberto, 25, suffered a right hamstring strain when he pinch-hit on August 24 at San Francisco, the same day he had been recalled from Round Rock for his third Major League stint of 2018 (also May 15-June 1 and June 10-13). He was on the disabled list from August 25-September 3. Alberto has gone 1-for-12 (.083) in 6 games/3 starts for Texas, making one start each at second base, third base, and shortstop. He spent the bulk of the year with Round Rock, batting .330/.346/.452/.797 (119-361) with 7 home runs and 58 RBI over 101 games for the Express. In 47 games at Triple-A after the start of July, Alberto batted .367 (65-177) with a .904 OPS figure.

Bibens-Dirkx, 33, has a 2-3 record with a 6.59 ERA (30 ER/41.0 IP) in 10 games/6 starts spanning three stints with the Rangers this season (May 24-29, June 19-July 8, July 20-August 4). He last pitched for Texas on August 3 vs. Baltimore, and his last start with the club came on July 8 at Detroit. He spent the balance of the campaign with the Express, going 3-6 with a 5.68 ERA (52 ER/82.1 IP) and 1.482 WHIP figure over 17 games/15 starts. He last pitched on Wednesday vs. Memphis, taking the loss (5.1 IP, 6 H, 5 R-4 ER, 3 BB, 7 SO, 2 HR, 100 pitches/58 strikes).

Calhoun, 23, will be in his second big league stint this season, as he was also with Texas from July 20-August 15, spanning Nomar Mazara's stay on the disabled list. Calhoun batted .275 with one home run and 9 RBI in 22 games for Texas since being promoted on July 20, the day Mazara was formally placed on the disabled list. He has spent the balance of the campaign at Round Rock, compiling a .294/.351/.431/.782 (127-432) slash line with 9 home runs, 32 doubles, and 47 RBI in 108 games. His 32 doubles finished tied for 5th-most in the Pacific Coast League, and he was also 5th in the league with a ratio of 10.00 plate appearances per strikeout.

The 26-year-old Sampson will be seeking his first Major League action since he was injured while warming up prior to a scheduled start while with Seattle on June 23, 2016 at Detroit. He spent the entire season with Triple-A Round Rock, going 8-4 with a 3.77 ERA (53 ER/126.2 IP) in 33 games/19 starts. The right-hander went 5-1 with a 2.34 ERA (22 ER/84.2 IP) over his final 14 starts with the Express, allowing 3 runs-or-less in all 14 outings. He last started and earned the win on Sunday at Iowa (6.0 IP, 5 H, 3 R-ER, 1 BB, 2 SO, 75 pitches/49 strikes). Sampson was originally received by Texas on a waiver claim from Seattle on November 2, 2016, and made 8 starts in the Minor Leagues last season as he worked his way back from flexor tendon surgery on June 30, 2016.

Pelham, 23, will be seeking his Major League debut. He combined to go 2-0 with a 3.66 ERA (19 ER/46.2 IP) in 47 relief appearances with High-A Down East and Double-A Frisco in 2018. The left-hander converted each of his 13 save opportunities and averaged 10.2 strikeouts per 9.0 innings. He last worked on Friday at Midland (1.0 IP, 1 H, 1 R-ER, 2 SO), the only run he has allowed over 5 appearances since August 21. Pelham held left-handed batters to a .206/.320/.302/.622 slash line in the Minors this season, and has surrendered just one home run in 250 plate appearances vs. left-handed batters in his Minor League career. Pelham was selected by Texas in the 33rd round of the 2015 June Draft out of Spartanburg Methodist College in South Carolina.

With the addition of Sampson and Pelham to the Major League roster, the Rangers now have a full 40-man roster along with 6 players on the 60-day disabled list.
