Giants activated 1B Travis Ishikawa from the 15-day disabled list; designated him for assignment.
Ishikawa, the hero of last year's NLCS, is now off the Giants' 40-man roster. He had been on the disabled list since the end of spring training with a lower back strain.
Rays third base prospect Richie Shaffer went 4-for-5 with three RBI Sunday in his first game for Triple-A Durham.
A first-round pick out of Clemson in 2012, Shaffer has shown plus power at each of his four minor league stops. That trend continued with two homers Sunday, the 42nd and 43rd of his career. The 24-year-old has plenty of potential but will need to cut down on his strikeouts before reaching the next level. He's already whiffed 49 times in 154 at-bats this season, including 15 punch-outs over his last 10 games.
Brett Lawrie is out of the A's lineup again Monday.
Lawrie hasn't played since Friday, and A's manager Bob Melvin acknowledged Sunday that the 25-year-old is "a little banged up." Max Muncy will handle the hot corner in Monday's afternoon opener against the Tigers.
Athletics activated UTIL Ben Zobrist from the 15-day disabled list.
Zobrist wound up missing just under four weeks following arthroscopic knee surgery. It was initially expected that he would be out until the middle of June. The versatile 33-year-old had batted .240/.304/.400 with one home run, five doubles, eight RBI, and eight runs scored through his first 14 games this season.
Padres first base prospect Cody Decker belted a pair of homers Sunday in a win for Triple-A El Paso.
Decker finished with six RBI, padding his season total to 31. The 28-year-old is fourth in the Pacific Coast League in homers (10), sixth in RBI and seventh in slugging percentage (.581). Decker also posted two homers in six RBI May 8 in a win against Las Vegas. Sunday was Decker's 13th career multi-home run game. He's hitting .304 in May after batting just .229 in April.
Athletics optioned OF Craig Gentry to Triple-A Nashville.
Gentry is sporting a horrendous .079/.163/.079 batting line in 43 plate appearances this season for the Athletics. He'll try to figure something out on the farm.
Rangers activated OF Josh Hamilton from the 15-day disabled list.
Hamilton is starting in left field and batting fifth Monday in his first game for the Rangers since the 2012 American League Wild Card round. The 34-year-old batted .364/.391/.545 with five doubles, one home run, six RBI, and nine runs scored on his 12-game minor league rehab assignment, and he's a good bet for high-level fantasy production back with Texas. Get him active in all standard fantasy leagues.
Brett Oberholtzer (blister) is expected to make a rehab start late this week at Triple-A Fresno.
Lance McCullers has been really good, so the Astros might ask Oberholtzer to make multiple rehab starts and then they could put him in the bullpen when he's deemed healthy. The left-hander has been on the disabled list since May 14 with a blister on his pitching hand.
