Description: Nate Jones, one of the White Sox's top closer candidates, threw about 40 pitches in a bullpen session Wednesday and felt fine, according to JJ Stankevitz of csnchicago.com. Jones has been out with a gluteal strain and is targeting Saturday for his Cactus League debut.
Insight: Chicago is in search of a new closer after trading Addison Reed to the Diamondbacks. The hard-throwing Jones has a good shot to win the closer job, as Ronald Belisario still hasn't arrived to camp due to visa issues and Matt Lindstrom aggravated an oblique injury. Scott Downs and rookie Daniel Webb are the other options.
Description: Cardinals closer Trevor Rosenthal will throw live batting practice Wednesday, according to Jenifer Langosch of mlb.com.
Insight: It's his final test as he attempts to return from a strained groin. Rosenthal averaged 96.4 mph with his fastball last season and should have great success as St. Louis' closer after assuming the role in late September and handling it through the postseason.
Description: According to mlb.com, Ronald Belisario still hasn't reported to White Sox camp due to visa issues.
Insight: Robin Ventura had no updates on the situation Tuesday, saying only that "it's gone dark." Belisario's chances of grabbing the closer role are all but gone. It will either be Nate Jones, Matt Lindstrom, Daniel Webb or Scott Downs closing games for the White Sox to start the season.
Description: New York closer Bobby Parnell (neck surgery, quad) is scheduled to pitch in a simulated game Thursday morning, according to espnny.com.
Insight: Parnell (5-5, 2.16 ERA, 22 saves) hopes to be ready for Opening Day. He isn't getting much attention from fantasy owners (26th closer off the board in Yahoo rankings), but if he's ready to go at the start of the season he'll have solid value.
Description: Mariners top prospect Taijuan Walker, who has been deailing with shoulder soreness, is scheduled to begin throwing again Thursday, according to Bob Dutton of The Tacoma News Tribune.
Insight: Walker arrived at camp with shoulder inflammation and was shut down last week. He had a 2.93 ERA and 160 strikeouts in 141 1/3 innings in the minors last season and is considered one of the top prospects in baseball, but is doubtful for the start of the season.
Description: Nate Jones, one of the White Sox's top closer candidates, could return from a gluteal strain as soon as Saturday, according to Scott Merkin of mlb.com.
Insight: Chicago is in search of a new closer after trading Addison Reed to the Diamondbacks. The hard-throwing Jones is competing with veterans Scott Downs, Ronald Belisario, Mitchelle Boggs and Matt Lindstrom for the job after posting a 4.15 ERA and 89 strikeouts in 78 innings last season.
Description: Braves left-handed reliever Jonny Venters (elbow) will throw a limited mound session Wednesday, according to Mark Bowman of mlb.com.
Insight: Venters missed all of 2013 after undergoing Tommy John surgery and is trying to make it back by late May or early June. He was one of the top setup men in the majors in 2010-11, posting a 1.89 ERA and 189 strikeouts in 171 innings.
Description: According to the Dallas Morning News, Rangers reliever Neftali Feliz is dealing with mechanical issues. He's not getting his arm extended enough to maximize his velocity.
Insight: Feliz underwent Tommy John surgery in August 2012 and only threw 4 2/3 innings last season. He saved 72 games with a 2.73 ERA and a 1.01 WHIP in 2010-11 before the team turned him into a starter in 2012, and the Rangers have him back competing for the closer job this season following his injury. Joakim Soria is the other candidate.

Insight: Chicago manager Robin Ventura said that Jones isabout a week behind his teammates and won't pitch in the early portion of the White Sox' Cactus League schedule. However, Ventura expects him to be ready for the season. Chicago is in search of a new closer after trading Addison Reed to the Diamondbacks. The hard-throwing Jones is competing with veterans Scott Downs, Ronald Belisario, Mitchelle Boggs and Matt Lindstrom for the job after posting a 4.15 ERA and 89 strikeouts in 78 innings last season.
Description: St. Louis reliever Jason Motte, who had Tommy John surgery on his right elbow last May, is doubtful for Opening Day but says April is a possibility, according to the St. Louis Post-Dispatch.
Insight: Motte led the National League in saves in 2012 with 42 but missed all of last season. Edward Mujica took over and saved 37 games but lost the job to Trevor Rosenthal late in the season. Rosenthal is expected to close this season with Motte eventually serving as the eighth-inning man.
Description: Cubs reliever Kyuji Fujikawa threw off a mound Monday for the first time since his Tommy John surgery, according to Jesse Rogers of espnchicago.com.
Insight: The 33-year-old Fujikawa only threw 12 innings last season after coming over from Japan but could eventually close for the Cubs when he returns in June or July. Jose Veras will begin the season as Chicago's ninth-inning man.
Description: Cardinals closer Trevor Rosenthal left Tuesday's workout with a right leg injury.
Insight: It doesn't appear to be serious and he left primarily for precautionary reasons. Rosenthal owns a triple-digit fastball and should be a top-five closer on a solid Cardinals roster. This bump in the road shouldn't change his fantasy value
Description: Yankees righthander Andrew Bailey won't be available to pitch until September at the earliest. He's still rehabbing his injured shoulder. SOURCE: Daniel Barbarisi, Wall Street Journal
Insight: Bailey signed a minor league deal with New York on Saturday. Even if Bailey were healthy, he wouldn't be a candidate to pitch the ninth inning. The former Red Sox and A's closer shouldn't be owned in any fantasy leagues.
Description: Reliever Andrew Bailey has agreed to an incentive-laden minor league contract with the Yankees, according to Buster Olney of ESPN.
Insight: Bailey had surgery to repair a torn capsule and damaged labrum in his right shoulder last summer. He threw just 44 innings and went 14-for-22 in save chances over his two seasons with the Red Sox. The New Jersey native will try to join the Yankees' bullpen by the middle of the season.
Description: Astros reliever Jesse Crain (2-3, 0.740 ERA, 1.145 WHIP with the White Sox) has a strained right calf and figures to start the season on the disabled list, according to Evan Drellich of the Houston Chronicle.
Insight: Crain and Chad Qualls were expected to battle for the closer's role for Houston, but it appears that Qualls will get the first shot by default.
