With the 2025 Texas Rangers season having come to an end, we shall be, over the course of the offseason, taking a look at every player who appeared in a major league game for the Texas Rangers in 2025.
Today we are looking at relief pitcher Caleb Boushley.

Caleb Boushley ended up with the unenviable role of the Rangers’ up-and-down long man and general “guy we call up when we need a body who can got multiple innings” pitcher in 2025.
Well, I say unenviable, but Boushley appears to have accumulated about 10 days worth of service time in his major league career (which consisted of six innings over three games the prior two seasons) before 2025. He now has 143 days of service time, which is more, by a lot.
The Rangers purchased Boushley’s contract on April 8, optioning Gerson Garabito to make room for him on the active roster.
Garabito, incidentally, ended up requesting his release from the Rangers later in the 2025 season so he could go pitch for Samsung in the KBO. Boushley, who became a free agent at the end of the 2025 season, will be spending the 2026 season in the KBO, though with KT Wiz. I hope the team’s slogan is, “Nobody beats the Wiz!”

Boushley was optioned to AAA Round Rock towards the end of April. The Rangers ended up recalling him five more times over the course of the season, and optioning him four more times. The last time the Rangers dropped him from the active roster, they designated him for assignment. He was claimed by the Tampa Bay Rays, for whom he did not pitch in the majors. The Rays designated him for assignment after the World Series.
Boushley was not good during his time with the Rangers. He threw 43 innings over 25 appearances, and really, you’d have expected him to pitch more often, given how much time he spent on the active roster, but then, the Rangers didn’t generally use him unless no one else was available or the game was so lopsided there was no point in using someone else.
Boushley put up a 6.02 ERA in those 25 games. He had an ERA of at least 5 in every month except May, when he put up a 4.38 ERA. He had a 5.04 ERA in the first half and an 8.31 ERA in the second half.
He did have significant home/road splits, putting up a 3.31 ERA at home and a 7.67 ERA on the road. If you’ve been paying attention to these write-ups and our discussions about how the Shed played, you will not be surprised to learn that Boushley was not a ground ball pitcher in 2025. He allowed a .234/.300/.281 slash line at home, with just 3 doubles and 0 home runs allowed, and a .345/.398/.558 slash line on the road, with 9 doubles and 5 homers allowed.

There was a guy named Bob Ferguson who had a 14 year career in the 1800s. His nickname was Death to Flying Things. That’s probably what we should be calling the Shed.
You may note that I said that Boushley was not a ground ball pitcher last year. I did not say he was a fly ball pitcher. That is because Boushley was, well, not a fly ball pitcher in 2025, either. He was a line drive pitcher. According to Statcast, 33.8% of the balls put in play against him were line drives. That’s not good.
Fangraphs, for what it is worth, has his line drive rate at 25.9%. There were 402 pitchers in MLB last year who threw at least 40 innings. Only nine of them had a higher line drive rate than Boushley. And five of those nine had line drive rates of either 26.0% or 26.1%. The worst line drive rate in the league was 27.6%, from AJ Smith-Shawver.
Not surprisingly, despite having a great defense behind him, Boushley had a ridiculous BABIP — .374, to be exact, tied with Mark Leiter, Jr., for second worst in baseball, behind Mason Montgomery.

Boushley put up a 5.94 xERA on the year, right in line with his 6.02 ERA. Not good. One isn’t surprised to see a -1.0 bWAR for him when you go to the B-R page.
However…Boushley was better than replacement level according to Fangraphs. Not a ton better — he has a 0.2 fWAR — but still, its positive.
This is because Fangraphs uses a FIP-based method for determining pitcher value, and Boushley put up a 3.85 FIP in 2025, along with a 3.95 xFIP. FIP is based on the assumption that pitchers do not have control over what happens when a ball is put into play but isn’t a home run, and thus is calculated based on home runs, walks, HBPs, and strikeouts. Whether a ball in play is a hit or an out is chalked up to the defense behind the pitcher and the overall randomness involved in small sample sizes.
In most cases, that works well enough. But there are some pitchers for whom that isn’t applicable. Sometimes a pitcher is giving up a high BABIP not because of randomness or defense but because he’s giving up rockets. And those edge cases don’t tend to affect the overall reliability of FIP because pitchers like that don’t stick around long enough to skew the numbers.

As is the case with Caleb Boushley, who will spend the 2026 season in Korea, getting paid.
