Ji-Man Choi 1B SEA 4 Hrs

Choi (leg) was designated for assignment by the Mariners on Thursday, Greg Johns of MLB.com reports.

This move comes on the same day that Choi underwent surgery to repair his broken right leg, suffered during Wednesday's Cactus League game. Choi is expected to miss 4-to-6 months as a result of the injury. Edgar Olmos (shoulder) took his place on the 40-man roster.

Collin McHugh SP HOU 4 Hrs

McHugh breezed through two scoreless frames Thursday in the Astros' Grapefruit League opener, striking out three while walking one against the Phillies.

"In terms of just kind of mental space, it's different because I've never been here, never broken camp with a team before," McHugh said. "It's different, but I'm excited because I'm honored to be called one of the five guys who gets the ball." The 27-year-old right-hander is likely to open 2015 as Houston's No. 2 starter behind Dallas Keuchel.

Edgar Olmos SP TEX 4 Hrs

Olmos was added back onto the Mariners' 40-man roster Thursday, Greg Johns of MLB.com reports.

The 24-year-old was designated for assignment by Seattle late last month and was subsequently claimed by Texas, but the Rangers' claim was reversed by MLB due to concerns over the health of Olmos' shoulder. He is now back on the M's 40-man, with Ji-Man Choi (leg) DFA'd to make room, but Olmos is no lock to open the season on schedule given the time lost to the shoulder issue.

Cliff Lee SP PHI 5 Hrs

Lee (elbow) went two innings in his spring training debut Thursday. He allowed a couple of singles and threw 16 of his 22 pitches for strikes.

Lee was making his first start since July 31 when he left that game with pain in his left elbow. He was working around 87-88 mph with his fastball Thursday, which is down from his typical velocity, but it is early in camp. He needs time to build up arm strength. The good news is that Lee said his elbow has felt normal thus far this spring. The Phillies are hoping to trade him at some point this season.

Josh Rutledge 2B/SS LAA 5 Hrs

Rutledge got the start at second base in the Cactus League opener against the Brewers on Thursday, going 1-for-2 with an RBI single in the contest.

Rutledge got the first chance at what is set to be a four-man audition at the keystone to replace Howie Kendrick. While the fact that he got first dibs doesn't necessarily mean he has a leg up on the competition, it is worth noting that Rutledge has the most experience of all the candidates, and could provide some power in what is traditionally a light-hitting position, as he carries a career ISO of .144.

Hector Santiago SP LAA 5 Hrs

Santiago threw two innings of work in the Cactus League opener against the Milwaukee Brewers on Thursday, allowing a hit and a walk while striking out one.

The first tuneup of the spring likely doesn't mean much, but throwing two scoreless frames is a good start for Santiago as he attempts to fill one of the two vacant spots in the rotation to open the season. Santiago really improved in the latter half of 2014, tallying a 2.98 ERA in 15 appearances (12 starts) but his ever-decreasing velocity, along with manager Mike Scoscia's tendency to limit his starts to six innings or less last season, could make him more of a matchup play if he cracks the rotation.

Tommy Medica 1B/LF SD 6 Hrs

Medica is 3-for-5 through San Diego's first two spring training games.

Medica is vying for the first base spot with the big league club this spring, but has an uphill battle. All signs point to incumbent Yonder Alonso retaining the starting role barring an injury. Still, if Medica has a good spring this year like he did in 2014, he could earn himself a spot on the major league roster.

Hunter Pence RF SF 6 Hrs

Pence (forearm) has been diagnosed with a non-displaced fracture of the left ulna and is expected to miss 6-to-8 weeks, Henry Schulman of the San Francisco Chronicle reports.

X-rays confirmed the Giants' fears; Pence did indeed suffer a fractured forearm as a result of being hit by a pitch during Thursday's Cactus League game. He will be fitted with a cast, and while it sounds like he could still make it back before the end of April, everything will depend on how quickly he progresses in the weeks ahead. Gregor Blanco and Juan C. Perez are the top in-house candidates to replace Pence in right, though the team could also go outside the organization to find a fill-in.

Yoenis Cespedes LF/DH DET 6 Hrs

Cespedes will not travel with the team for Friday's game but is expected to return to action Saturday, Jason Beck of MLB.com reports.

A bout of lower-back tightness resulted in Cespedes' scratch from Thursday's lineup, but it sounds like the team expects the discomfort to subside in short order. Cespedes made quite an impression in his Tigers debut Tuesday, crushing a grand slam off Oliver Drake in his second plate appearance.

Hunter Pence RF SF 7 Hrs

The Giants' staff fear that Pence has a broken left forearm, Hank Schulman of the San Francisco Chronicle reports.

Pence's official timetable will likely become more clear once the X-rays come back, but it's believed the exam will confirm the break as a result of a hit by pitch Thursday. Look for the team to provide an update in the near future.
