Dayan Diaz signed with the Astros as a 16-year-old in the 2005 international signing period. He spent the next three seasons pitching in the Venezuelan Summer League, pitching very well in the last two seasons where his ERA was 2.05 and 1.85. He would miss the entire following season after having Tommy John Surgery.

When he returned in 2010 the Astros brought him stateside, but he only pitched in two games that season at the complex level. When he was 22-years-old he was assigned to the New York-Penn League where he then went on a run of strong seasons pitching out of the bullpen, posting ERA’s of 1.98, 1.85 and 3.00 before being released by the Cubs following the 2013 season. The then 25-year-old signed with the Boston Red Sox and continued to find success in the bullpen, posting a 1.80 ERA in 2014 and a 1.73 ERA in 2015, but couldn’t quite find his way into the big leagues despite all of his success.

He signed with the Reds as a minor league free agent in November and was sent to Louisville to pitch out of the Bats bullpen. In 12 games he posted a 1.88 ERA over 14.1 innings pitched. He walked four batters and had seven strikeouts. With the state of the Cincinnati bullpen, after years of strong performances the 27-year-old was finally given a chance to pitch in the big leagues.

On Sunday afternoon Dayan Diaz would finally make his Major League debut against the Seattle Mariners. He threw a shutout inning, allowing one hit. He threw 14 pitches, eight of which were strikes.

The right hander averaged 93.6 MPH on his fastball and topped out at 94.5 according to Brooks Baseball. 12 of the 14 pitches that he threw on the day were fastballs with the other two pitches being sliders. Both of the sliders were thrown at 85 MPH, with one being swung at and missed and the other being taken for a called strike. The slider and fastball both showed good movement on the day.

It was nearly 10 years in the making for Diaz, but the Columbian native finally got his shot in the big leagues. With how the season has gone for the Reds, with good performance there should be plenty of opportunity for the righty to remain in the big leagues.
