Boston Smith Catcher: 5 HR in His Double-A Debut
▶ Watch this story in under a minute — or read on.
Three organizations in five months — and then he hits five home runs in his debut week with the Arkansas Travelers. Boston Smith’s story is a lesson in fast adjustment for every catcher who’s ever played somewhere new.
Boston Smith stepped into the batter’s box at Dickey-Stephens Park on August 3rd as a brand-new Mariners catcher. He had been traded two days earlier, part of the three-player return Seattle received for pitcher Luis Castillo. He had barely unpacked before homering in his first game. Then, as a bonus, he did it again on Sunday.
Six games into his Arkansas debut, Smith had already homered five times. The Texas League named him Player of the Week for August 3–9, and every one of those home runs came at a park scouts consider one of the toughest on hitters in the league.
| Double-A debut week | August 3–9, 2026 |
|---|---|
| Games | 6 |
| Hits | 8-for-21 |
| Home runs | 5 |
| RBI | 9 |
| Batting average | .380 |
| Slugging percentage | 1.095 |
Smith is 23 years old. The Washington Nationals drafted him in the sixth round of the 2025 MLB Draft with the 171st overall pick. Then the Nationals traded him to the White Sox in March 2026. He had not thrown a single pitch in Washington’s system.
The White Sox shipped him to Seattle on August 1st, part of the Luis Castillo deal. Three organizations in roughly five months.
Before all of that, Smith spent four years at Wright State University, a mid-major program in Dayton, Ohio. In his final season he broke the school’s home run record. Three All-American panels honored him for it.
| Wright State | 2025 senior season |
|---|---|
| Home runs | 26 — program record |
| RBI | 70 |
| OPS | 1.274 |
The NCBWA named him National Hitter of the Month for May 2025 after posting some of the most powerful numbers in all of Division I baseball.
Troublesome is the fact that even with those he still wasn’t a top draft pick. Still, he kept hitting.
From Dayton to North Little Rock
Five stops in five years — and the last three came in barely five months.

Smith’s 27 home runs lead all Minor League catchers. His walk rate sits above 20 percent — one of the most patient approaches in the minors.
| 2026 season | Three levels, four clubs (through Aug. 9) |
|---|---|
| Games | 85 |
| Home runs | 27 |
| RBI | 67 |
| Walks | 77 |
| AVG / OBP / SLG | .297/.450/.626 |
| OPS | 1.076 |
Scouts are still watching to see whether his defensive game behind the plate catches up to his bat. He has also played the outfield corners. But at every level he has climbed, pitchers have not found an answer for him.
So after Boston Smith went 8-for-21 with five home runs that week, eyes turned and he was recognized. He was competing for a new organization. He was playing at a park built to humble hitters.
What a catcher can learn from this
Boston Smith had two days to get comfortable. Then he played.
That kind of quick adjustment is one of the things the catching position demands more than any other. The catcher has to know the staff. The catcher has to know what the umpire is calling. And the catcher has to read the game from a completely different angle than everyone else on the field. When you are new, you do all of that from scratch.
Smith did not wait until he felt comfortable. Instead, he just started learning.
That is a skill you can build at practice, long before anyone trades you anywhere. Every time you catch a pitcher you have not worked with before, you are practicing this. Every time a coach changes the signs, you are practicing it. Every time you play in an unfamiliar park, you are practicing it.
The catchers who stick — at any level — are the ones who learn fast and then go to work. This week in North Little Rock, Boston Smith showed what that looks like.
You can do that on Thursday.
Try this at your next practice
- New battery partner reps. Pair with a pitcher you have not caught before. Call an entire inning of pitches using only what you learn from his warm-up. No pre-game conversation about what he throws. Practice reading arm slot, release point, and movement — exactly what you would do if you were traded tomorrow.
- Sign switch drill. Mid-practice, have your coach change one of the standard signs without warning — replace it mid-session. See how quickly you can incorporate the new sign without slowing the game down. Fast learners win this drill. The goal is one missed sign, then zero.
- Unfamiliar-park adjustments. When you travel to a new field, arrive early and stand behind the plate. Look at the background beyond the pitcher’s mound. Watch how the ball comes out of the delivery against that backdrop. Learn the park before the first pitch. Smith had two days. You might have twenty minutes. Use them.
