Astros select Raynel Delgado from minor league trade with Rays
Delgado arrives as Houston adds depth to an infield while sitting 31-39 with a -38 run differential, but his promotion does not address the rotation issues that have allowed 353 runs this season.
Slater arrives with a .209 AVG and .233 xwOBA in limited Triple-A action, positioned as a bench depth piece against Boston's left-handed starter tonight. TB (37-25, +7 run diff) is 3-7 in their last 10 despite leading the AL East, making roster flexibility more valuable than a marginal offensive upgrade.
Matz's 5.48 ERA and .373 xwOBA across 37.1 IP since returning mid-May forced the move, leaving Tampa Bay (37-23, +11 run diff) with Martinez (2.29 ERA) and Rasmussen (3.36 ERA) as reliable rotation anchors heading into tougher stretches.
Wantz posted a 27.00 ERA in minimal 2026 action before designation, making this a routine roster move for Tampa Bay's rotation-by-committee approach led by Martinez (1.62 ERA, 5-1) and Rasmussen (3.36 ERA, 55 SO).
Rangers Place Evan Carter On 10-Day IL With Oblique Strain
Carter exits with a .176 AVG and .294 xwOBA across 66 games, so Texas loses minimal offensive production but depth in the outfield. Freeman (no 2026 stats available) takes the roster spot as the Rangers sit 34-35 and face Boston tonight with deGrom on the mound.
Rangers Select Joe Ross From Triple-A, Designate Michel Otañez
Ross has no MLB action this season (0 IP, 19.64 ERA in Triple-A context) and enters a rotation where deGrom (3.18 ERA, 84 SO) anchors a staff trying to climb out of third place in the AL West.
MLB Over-35 Hitters Face Steepest Production Drop-Off in Decades
Age-related decline in MLB hitting has accelerated beyond historical norms, but current roster construction shows teams still value veteran bats: Angels have Mancini (.070 AVG in limited action), Rangers deal Martin Jr. to Rockies at 31, and Astros explicitly refuse to trade 31-year-old Alvarez despite his continued elite production (.316 AVG, 0.493 xwOBA).
Martin, 31, represents depth movement for a Rangers team sitting 32-33 with a +14 run differential. Colorado, mired at 24-42 with a -99 run diff, adds a utility option but addresses no rotation or offensive production concerns.
Haggerty batted .159/.182/.182 across limited action before designation, making this a minor roster depth move. Texas remains at 31-33 with a +4 run differential despite the transaction.
