If history repeats itself, Thursday was an ominous development for Chase Headley.
Headley left Thursday's game against the Nationals with a right calf strain. After flying out in the top of the second inning in his first and only at-bat, Headley was replaced by Alexi Amarista at third base when the team took the field in the bottom half of the inning.
Calf strains are worrisome enough, but compounding it is the fact that Headley dealt with the exact same injury this spring. The calf bothered him for a month, forcing him to miss much of the early exhibition season. He didn't miss any regular season games due to the injury, but his slow start -- Headley was hitting just .186/.250/.314 on the year before Thursday's setback -- could have been a result of his spring issues.
Given that Headley missed so much time his first go-round with the injury, it's not hard to imagine him winding up on the disabled list as a result of the re-injury. If that does happen, the most likely candidate to replace him in the lineup is Amarista. The 25-year-old doesn't offer much in the way of batting average or power, but he stole 120 bases in his minor league career and has three stolen bases in four attempts so far this year. Even so, Amarista shouldn't be on fantasy radars outside of the deepest NL-only leagues.
An interesting alternative, if the Padres desire to inject a more potent bat into the everyday lineup, would be to take a look at Yonder Alonso at the hot corner. Alonso was seen taking ground balls at third base before a game earlier this month, and he actually played an inning at third in a game against the Rockies last week. Playing Alonso at third base would allow Padres manager Bud Black to play a more offensively minded player -- Tommy Medica, Xavier Nady or, when Carlos Quentin returns, Seth Smith -- at first base.

Griffin Seeking Second Opinion
Griffin was shut down this spring with a flexor muscle strain in his right elbow, but he recently began doing exercises to strengthen the muscle in hopes of working his way back by May.
Instead, the 26-year-old will see a doctor next Tuesday to get a second opinion on his elbow. It became apparent during strengthening exercises that the elbow still wasn't 100 percent, necessitating the return trip to the exam room.
Anytime an elbow is involved the potential for requiring Tommy John surgery exists, but it's even more possible given Griffin's injury. For context, the flexor strain is the same injury Josh Johnson was diagnosed with in early April before recently undergoing the second Tommy John surgery of his career on Thursday.
Griffin isn't to that point yet -- the second opinion could show nothing wrong with the muscle, and Griffin could be back in the A's rotation by mid-May. But given the rash of Tommy John surgeries lately, it wouldn't be surprising if Tuesday's opinion bore bad news, either.
Fister Set For Rehab Start
In more pitcher-friendly news, Doug Fister is scheduled to make his first rehab start this weekend.
Fister, who's working back from a lat strain that's kept him from regular season action thus far, will start for the Nationals' High-A Potomac affiliate on Sunday. He'll make the start after he was able to throw a problem-free bullpen session on Thursday.
Fister will throw four innings in the start, and he'll need at least one more before rejoining the Nationals rotation. As it stands, the target date for a return is May 7, which is exactly two rotation turns from Sunday's rehab start.
Unless the Nats' rotation suffers another injury before his return, the most likely candidate to lose his rotation spot is Taylor Jordan. The 25-year-old is 0-3 with a 6.23 ERA and 1.71 WHIP through his first four starts. Tanner Roark, who also had to earn his spot this spring, has been much better, going 1-0 with a 3.80 ERA and 1.44 WHIP in his four starts.
