The Astros are adding some catching depth, bringing in Matt Thaiss on a minor league contract and sending him to Triple-A Sugar Land, according to the MLB.com transaction log. Thaiss had been released from a non-roster deal with the Red Sox last week.
Thaiss, a first-round pick in 2016, has logged parts of seven big league seasons, including six with the Angels. Over just under 1,000 career plate appearances, he has hit .210/.320/.332.
That kind of production can work for a backup catcher, but the glove has not given him the kind of edge teams usually want in that role. He blocks well, but his pitch-framing grades have been mediocre and his arm has graded below average.
Early in his career, the Angels tried him at third base, though he has been a full-time catcher for the last few seasons.
The left-handed hitter spent this year at Triple-A Worcester in Boston’s system, and the bat never really got going. He hit .201/.314/.313 with three home runs in 170 plate appearances. His plate discipline stayed in its usual shape, but he didn’t drive the ball especially well and finished with a .224 average on balls in play.
Houston’s catching production has been a problem this season. Yainer Diaz and Christian Vázquez have combined for a .208/.254/.343 line, which ranks bottom five in MLB, and the position has also seen limited at-bats from César Salazar and Collin Price.
Price is still on the 40-man roster but has been on the Triple-A injured list since the middle of June. Salazar, who was outrighted last month, landed on the minor league IL this week.
Thaiss looks like a depth move, and he’d likely be the next man up if either big league catcher goes down before Price or Salazar return.

Kristian Campbell Is Suddenly Forcing A Tough Red Sox Decision
Kristian Campbells season has been uneven enough that Triple-A Worcester started to feel like a reset point, but the recent stretch has changed the conversation. After Boston committed to him with an eight-year, $60 million deal at the start of the 2025 season, Campbell has begun showing the kind of offensive progress the Red Sox were hoping would show up more consistently, hitting .273 with an .805 OPS in the second half and climbing above .300 in July with a 1.006 OPS.
The better contact has come with more impact, too, as Campbell has recently turned in multiple home runs and even a 2-for-3 game with a homer during this surge. For a player the Red Sox still view as part of their long-term picture, that kind of production creates a familiar roster dilemma: keep letting him build momentum in Worcester, or keep the door open for another look in Boston while the bat is finally starting to look like it belongs.

Red Sox Fans Turned Fenway Into Absolute Chaos Against Toronto
Fenway Park got a little louder and a lot more unhinged during Bostons game against the Toronto Blue Jays, as Red Sox fans joined the tarps off movement and turned the stands into a moving sea of bare chests and waving shirts. The scene stretched across the ballpark, giving the kind of edge-to-edge energy that usually belongs to October, not a regular night when the crowd is simply looking for a way to push its team forward.
The stunt has become a recognizable bit of baseball fan culture after starting in college football and catching on in MLB through St. Louis Cardinals supporters, who eventually got a dedicated high-energy section at Busch Stadium. Bostons version fit the moment at Fenway perfectly, with fans leaning into the chaos and making sure the atmosphere felt less like a routine divisional game and more like a full-on rally.
