Description: Giants outfielder Hunter Pence will miss six-to-eight weeks after an X-ray revealed Thursday he has a fracture in his left forearm.
Insight: Pence took a pitch in the arm just above the wrist on Thursday which caused the break. With the six-to-eight week timetable, fantasy owners can't really depend on any production from Pence in April. Pence has played in 383 straight games, so that will come to an end. Gregor Blanco will see most of the left over playing time in right field.
Description: Red Sox manager John Farrell told the Boston Globe that Rusney Castillo's oblique is feeling "much better".
Insight: Castillo suffered a strained left oblique muscle after Tuesday's game. It's a minor strain, so it will not affect his status for Opening Day. Castillo and Mookie Betts are fighting for the starting center field spot.
Description: Tigers outfielder J.D. Martinez went 3-for-3 versus the Braves on Thursday.
Insight: Martinez was great last season, slashing .315/.358/.553. It does, however, seem unlikely that he will maintain those numbers, and it also seems possible that he moves from fifth to sixth in the lineup with Yoenis Cespedes batting fifth. If owners can get him in a middle-round, by all means draft Martinez, but don't expect him to hit .300 again.
Description: Angels center fielder Mike Trout has a plan to cut down his league-leading 184 strikeouts from last season.
Insight: Trout told the Los Angeles Times that he plans to be more aggressive early in counts this spring. He said he believes swinging at more first pitches will lead to fewer punchouts. Regardless, there is hardly an argument that Trout shouldn't go No. 1 overall in fantasy drafts this season.
Description: The Dodgers are willing to pay half of outfielder Andre Ethier's salary in order to trade him this spring according to CBS Sports.
Insight: Ethier is due $56 million over the next three years, so Los Angeles is offering to pay about $28 million of that. Matt Kemp left in free agency over the winter, but with youngster Joc Pederson expected to play center field, the Dogers still have the problem of too many outfielders. Time will tell if Ethier gains any interest from other clubs.
Description: Angels outfielder Josh Hamilton could enter a rehabilitation program for his drug abuse according to the Los Angeles Times.
Insight: A four-person panel is currently split on whether he should enter rehab. An arbitrator will join the group to break the tie. It is also possible that the league considers Hamilton a fourth-time offender, which would mean a year-long suspension. New commissioner Rob Manfred, however, will ultimately make that decision. To say there is major risk in drafting Hamilton for your fantasy team this season seems to be the understatement of the year.
Description: Padres outfielder Matt Kemp was 0-for-3 in his Padres debut on Wednesday.
Insight: Kemp struck out once and grounded into a double-play. Kemp had a great bounce-back season a year ago, hitting .287/.346/.506 with 25 home runs and 89 RBI. Fantasy owners should be wary, however, that San Diego's Petco Park is a much more pitcher-friendly park than Dodger Stadium.
Description: Dodgers outfielder Joc Pederson was 2-for-2 with a double and a run in two at-bats on Wednesday.
Insight: Pederson is projected to be the Dogers Opening Day center fielder. He had just four hits in 28 at-bats last September, so it is nice to seem him have more success. The expectations are high on this 22-year-old.
Description: 27-year-old rookie Rusney Castillo had pain in the left side of his body during Tuesday's spring training game according to the Boston Globe.
Insight: Team doctors will evaluate Castillo Wednesday morning. Castillo is battling Mookie Betts for the starting center field job, but if the Red Sox are able to deal Shane Victorino, both Castillo and Betts could have starting roles.
Description: Braves center fielder Melvin Upton will likely begin the season on the disabled list after being diagnosed with sesamoiditis.
Insight: Sesamoiditis is a condition when the bone behind the foot becomes inflamed. Upton will not resume baseball activities until the beginning of April at the earliest, which is unforunate because he is need of a bounce-back year. Eric Young Jr., Eury Perez, and Zoilo Almonte are the candidates to fill in for Upton.
Description: Nationals manager Matt Williams told CSN Washington that Harper will likely hit somewhere in the middle of the lineup.
Insight: Harper mostly hit sixth last season despite his complaints. Harpes is injury prone, having missed 106 games over the last two seasons, but Williams clearly expects Harper to take his game to another level. Fantasy owners would love that.
Description: Nationals center fielder Denard Span is cleared for full workouts according to CSN Washington.
Insight: Span had surgery in December to repair a sports hernia, but he is 100 percent recovered. He was a very good fantasy player last season, hitting .302/.355/.416 with 31 stolen bases and 94 runs. Span was particularly good in the second half, hitting .346/.403/.459 after the All-Star break.
Description: Angels center fielder Mike Trout told the Los Angeles Times that he wants to increase his stolen bases and cut down on his strikeouts in 2015.
Insight: This is music to fantasy owners' ears. Trout stole just 16 stolen bases last season after swiping 33 in 2013 and 49 in 2012. He also led the AL with 184 strikeouts last season. Fantasy owners would love to see another 30-steal season, but regardless, it's hard to argue Trout isn't the first overall pick off draft boards this spring.
Description: Giants center fielder Angel Pagan (back surgery last September) says he's without restrictions and feels good, according to beat writer Alex Pavlovic.
Insight: OK, everyone feels good the first day of spring training. Pagan hasn't played more than 96 games in each of the last two seasons. He may also lose his spot at the top of the lineup to Norichika Aoki, so drafting Pagan comes with multiple red flags.
Description: Royals outfielder Alex Gordon (right wrist surgery) has been cleared to threw and take 15 swings Tuesday.
Insight: Gordon underwent extensor retinaculum repair in january He's a four-time Gold Glove winner who batted .266 with 19 HR, -74 RBI, 87 runs and stole 12 bases. He's capable of more and this wrist injury, which may have happened back in July, could have been the culprit. He could be ready for Opening Day.
Description: Angels general manager Jerry Dipoto told the Los Angeles Times on Friday that left fielder Josh Hamilton could miss up to 12 weeks with his shoulder injury.
Insight: Hamilton's original timetable was six-to-eight weeks, so that's quite a difference. The weird thing is Hamilton hasn't suffered a setback; Dipoto has simply just changed the prognosis. This situation just indicates that the Angels really have no idea when Hamilton will be back, and he may not return until May.
