Jake Diekman recently underwent the second of three ulcerative colitis surgeries to remove and rebuild his colon.
Diekman lost about 10 pounds as a result of the procedure. He'll have the third and final surgery on June 9 at the Mayo Clinic in Rochester, Minnesota. The hope is that Diekman will resume a throwing program in late June and rejoin the Rangers' bullpen sometime in the second half. Apr 21 - 12:00 PM

Rangers placed LHP Jake Diekman on the 60-day disabled list.

Diekman underwent colon surgery in January and has two more procedures scheduled for April and June. The left-hander is hoping to be able to contribute shortly after the All-Star break.
Feb 14 - 4:57 PM

Jake Diekman (colon surgery) said Tuesday that he expects to be pitching by the All-Star break.

Diekman underwent surgery in January to remove his colon, but he's present for the start of Rangers' camp this week. He still has two more surgeries ahead of him in April and June, but he's still planning to contribute out of the Rangers' bullpen this season. It would be quite the comeback.
Feb 14 - 2:31 PM

Rangers general manager Jon Daniels said that Jake Diekman (abdomen) plans to be present for the start of spring training.

Diekman continues to recover after undergoing surgery to remove his colon near the end of January. He is not expected to be healthy enough to contribute to the Rangers until later this summer, but will at least attend spring training as he continues to work his way back from the major surgical procedure.
Feb 8 - 5:03 PM

Jake Diekman underwent successful surgery to help alleviate ulcerative colitis on Wednesday.

Diekman was under the knife for four hours as doctors removed a colon damaged by ulcerative colitis. This is a disease which has affected him since the age of 11. The 30-year-old is expected to miss a healthy chunk of the 2017 campaign as he recovers from the procedure. This past season, Diekman pitched to a 3.40 ERA, 1.17 WHIP and 59/26 K/BB ratio across 53 frames.
Jan 25 - 4:44 PM

Jake Diekman will have surgery on January 25 to help alleviate ulcerative colitis and is expected to miss at least half of the season.

That's too bad. Diekman has been open about his fight with the illness and will hopefully get some relief from the procedure. He turns 30 next week and posted a 3.40 ERA and 59/26 K/BB ratio over 53 innings last season. He'll be a nice weapon for the Rangers' bullpen once he's back to full health. The Rangers and Diekman agreed to a one-year, $2.55 million deal last week to avoid arbitration.
Jan 17 - 1:37 PM

Rangers and LHP Jake Diekman avoided arbitration by agreeing to a one-year, $2.55 million contract.

As anticipated, the deal was right around the $2.5 million midpoint between the figures that each side filed at on Friday. The 29-year-old southpaw registered a 3.40 ERA, 1.17 WHIP and 59/26 K/BB ratio across 53 innings in 2016.
Jan 13 - 11:00 PM

Jake Diekman requested $3.1 million and was offered $1.9 million by the Rangers when arbitration figures were exchanged on Friday.

It's unusual to see a player and club so far apart when submitting their figures for arbitration. It does leave a lot of room in the middle to negotiate a deal though, rather than heading to a hearing. He was projected by MLBTradeRumors.com to earn $2.6 million through arbitration, which is right around the $2.5 million midpoint.
Jan 13 - 9:31 PM

Jake Diekman pitched a scoreless ninth against the Rockies for his third save Monday.

Sam Dyson had the night off after working the previous two days. Diekman has a 2.25 ERA in his setup role this year. He'll be a big weapon for the Rangers if they make it back to the postseason.

Rangers activated LHP Jake Diekman from the 15-day disabled list.

He missed the last couple weeks with a lacerated left index finger. Diekman holds a 2.73 ERA, 0.97 WHIP and 36/13 K/BB ratio in 33 innings of relief this season.

Rangers placed LHP Jake Diekman on the 15-day disabled list, retroactive to July 6, with a lacerated left index finger.

Diekman figures to return when first eligible, unless it's a really nasty cut. The 29-year-old southpaw holds a cool 2.73 ERA, 0.97 WHIP, and 36/13 K/BB ratio in 33 innings of relief this season for Texas.

With Sam Dyson needing another day off, Jake Diekman preserved a two-run lead in the ninth for his first career save Thursday against the Astros.

The Rangers wanted to stay away from Dyson for two days after he pitched three straight days earlier in the week (including a 30-pitch outing on Tuesday). Diekman's first save came in his 245th career relief appearance. He has a 1.83 ERA in 44 1/3 innings since arriving from the Phillies with Cole Hamels last summer.

Rangers and LHP Jake Diekman avoided arbitration by agreeing to a one-year, $1.225 million contract.

The deal also includes incentives which could push the total even higher. The figure is closer to the $975,000 that the Rangers filed at than it is to the $1.55 that the southpaw was seeking. He'll again function in a setup capacity in front of closer Shawn Tolleson for the Rangers
Fri, Jan 29, 2016 08:20:00 PM

Jake Diekman requested $1.55 million and was offered $975,000 by the Rangers when arbitration figures were exchanged Friday.

MLBTradeRumors.com is more in line with the club with their $1 million projection. Diekman is arbitration-eligible for the first time.
Fri, Jan 15, 2016 05:42:00 PM

Left-hander Jake Diekman was traded from the Phillies to the Rangers in an eight-player deal.

Diekman has had a rough year, with his always shaky control going from bad to worse. Still, he has one of the best arms of any left-handed reliever in the game, which explains how he's struck out 225 batters in 173 1/3 innings as a major leaguer. The Rangers will ask for less and potentially get more out of him than the Phillies did. Plus, he's under control through 2018.
