2025 Fantasy Outlook
Montgomery hoped to parlay a strong 2023 season, which included a World Series ring with the Rangers, into a lucrative long-term deal but one never materialized. The left-hander eventually signed with Arizona late in spring training, and the non-traditional ramp up had a deleterious effect on Montgomery. He ended the season with a 6.28 ERA over 25 outings (21 starts), last among pitchers with more than 140 innings. Unsurprisingly, he exercised a 2025 option and joins the competition of six legitimate starters. Nothing is guaranteed for Montgomery, who was hit hard (41 percent), as opponents teed off on his sinker, the pitch he throws most. His walk rate jumped (6.2% to 8.3%), while his strikeout rate plummeted (21.4% to 15.6%). Warning flags abound, but Montgomery was one of 14 pitchers with at least 550 innings pitched and a sub-3.65 ERA from 2020-23. Read Past Outlooks

Lands on 60-day IL
The Diamondbacks placed Montgomery (elbow) on the 60-day injured list Wednesday, Alex Weiner of ArizonaSports.com reports.
ANALYSIS
Montgomery is set to undergo Tommy John surgery sometime next week, which will end his 2025 season before it even starts and will likely force him to miss part of the 2026 season. The Diamondbacks will award his spot on the 40-man roster to lefty Jalen Beeks, who signed a one-year deal with the club. Montgomery is scheduled for free agency after the season.

Much has been decided in the National League over the last few days, including the Giants' fifth starter job, which was won by Landen Roupp.

Every team in the National League West has a battle at the back of its rotation this spring, though the Dodgers' contest has just been won by Dustin May.

Todd Zola tries to remove volume from the equation when determining the value of pitchers, and finds that the market may have over-corrected on Logan Webb.

For the second straight season, Montgomery began the year pitching for a team with playoff aspirations but was traded at the deadline to a team a team still in contention. Of course, last season ended with Montgomery celebrating a World Series win with the Rangers. Montgomery began the season recording a 3.42 ERA and 1.25 WHIP for the Cardinals, fanning 108 in 121 frames. After joining Texas, Montgomery posted a 2.79 ERA and 1.09 WHIP punching out 58 in 67.2 innings. His 21.4 percent strikeout rate is below average, but the southpaw is frugal with free passes and does a good job keeping the ball in the yard. Montgomery is durable, with his 94 starts over the past three seasons tied for sixth most in MLB. A low strikeout rate hurts Montgomery's fantasy appeal, but it also keeps his cost of acquisition affordable. There is always risk a pitcher of this ilk experiences some misfortune, but he has displayed the ability to buffer ratios in a rotisserie league format.

Latest Fantasy Rumors

Trade interest increasing
According to John Gambadoro of Arizona Sports 98.7 FM Phoenix, the Diamondbacks have recently received trade interest from a few teams for Montgomery.
ANALYSIS
The left-hander surrendered five runs while recording just one out during his spring debut March 8, but the camp reports have otherwise been encouraging for the 32-year-old. Montgomery exercised his $22.5 million player option for 2025 after he posted a 6.23 ERA in 25 appearances last year, so Arizona may need to include some cash in order to help facilitate a trade.
