Leo Rivas dazzles in his major league debut for the Mariners

Leo Rivas made his major league debut in the finale against the Diamondbacks, allowing Dylan Moore to rest on Sunday. Rivas helped spark a rally in the third inning, with a lead-off triple. He hammered an 0-2 pitch down the right field line that hit the fence. Rivas put his speed on full display, bolting around the bases before sliding into third with a triple. That triple was Leo Rivas first big league hit and he eventually would score on an RBI single by Julio Rodriguez.

Leo Rivas played well in the field in his MLB debut

On top of picking up his first hit and the first run of his career, Leo Rivas also made a couple of nice plays in the field. He made a good break on a ground ball hit to the hole at third base and made a sweet one-hop throw to France to retire former Mariner Eugenio Suarez. He then made a routine catch on a soft blooper hit to up the middle by Corbin Carroll on the next play. Rivas showed he can do a solid job of holding down shortstop.

What to expect from Leo Rivas going forward

The Mariners have a nice backup option in Leo Rivas at shortstop, as was seen on Sunday by his play in the field and his speed around the base paths. Rivas' speed could be a real weapon late in games if the Mariners need someone to steal a base. He will likely continue to split time with Dylan Moore at shortstop until J.P. Crawford returns from the injured list.

Leo Rivas made the most of his debut with the Mariners

Rivas played well overall in his debut and was able to accomplish a feat no Mariner had since Yuniesky Betancourt, by tripling in his major league debut. Rivas' first hit of his career was certainly a fun experience for him, as he cruised around the bases, and went into third base with a stand-up triple. He also became the 999th Mariner to appear in a baseball game.

With his performance, Rivas showed he can hang in the big leagues

Seeing Rivas play as he did today in just his first major league start at shortstop was impressive. For his first game, Rivas looked like a seasoned pro. Today he showcased his bat, glove, and speed, giving fans a thrill. Hopefully, Rivas can stick around and continue to make an impact at the big league level.
