Gordon Wittenmyer, who serves as a beat writer for the Chicago Sun-Times, explains this situation:
Cubs manager Dale Sveum said he anticipates right-hander Scott Baker getting his first spring start sometime in the middle of March, then opening the season on the disabled list and – barring setback – making his Cubs debut sometime in mid-April.
Baker underwent Tommy John reconstructive elbow surgery on April 17 of last season, so he’ll be a full 12 months removed from the procedure when he first takes the mound for Chicago.
The 31-year-old right-hander signed a one-year, $5.5 million free agent contract with the Cubs in November and could become trade bait around this year’s July 31 deadline if he can get back on track quickly.
Baker had a 3.14 ERA, 1.17 WHIP and 123/32 K/BB ratio in 134 2/3 innings with the Twins in 2011.
The Rockies announced on Monday that outfielder Carlos Gonzalez and pitcher Tyler Anderson were placed on the 10-day disabled list. The club activated reliever Chad Qualls from the disabled list and recalled reliever Jairo Diaz from Triple-A Albuquerque.
Gonzalez, 31, is dealing with a strained right shoulder. He’s in the midst of his worst season, batting .221/.300/.348 with six home runs and 20 RBI in 277 plate appearances. Gonzalez is a free agent after the season and has been commonly brought up in trade discussions, but his latest injury and underwhelming season will make it difficult for the Rockies to get anything meaningful in return this summer.
Anderson, 27, has inflammation in his left knee. He dealt with a knee problem earlier this season, so the injury seems to have been reaggravated. The lefty has an ugly 6.11 ERA with a 63/23 K/BB ratio in 63 1/3 innings this season.
Qualls, 38, went on the disabled list earlier this month with back spasms. He had previously been dealing with forearm inflammation, so it’s been a rough year for the veteran. He is carrying a 4.60 ERA with a 9/5 K/BB ratio in 15 2/3 innings.
Diaz, 26, hasn’t appeared in the majors since 2015. He has appeared in only eight games at Triple-A as he opened the season on the disabled list after undergoing Tommy John surgery last year. So far, Diaz has allowed three earned runs on seven hits and two walks with nine strikeouts in 7 2/3 innings.
White Sox reliever Zach Putnam underwent Tommy John surgery last week, CSN Chicago’s Dan Hayes reports.
Putnam, 29, had been on the disabled list since late April with a right elbow injury. He was cleared to begin throwing last month but was shut down after experiencing more elbow discomfort earlier this month. Putnam had surgery on his right elbow last August to remove a bone fragment as well, so it was an issue that had been nagging him for more than a year.
Putnam appeared in only seven games this season, giving up one run on two hits and a walk with nine strikeouts in 8 2/3 innings. The White Sox won’t be able to count on him until the middle of next season at the earliest.
