Gonsolin was a two-way player at St. Mary's, who was eliminated last weekend in the regional round of the 2016 NCAA Baseball Tournament.
In 2016, the 6'2, 180-pounder had a 3.86 ERA in 18 games as a senior, including five starts, with 39 strikeouts and 16 walks in 42 innings. He also hit .307/.400/.476 with seven home runs, nine doubles and 30 walks in 57 games, playing the outfield when he didn't pitch.
Gonsolin only pitched a total of 155 innings in four years in college.
He also played in the Northwoods League. His college coach Eric Valenzuela last August gave a glowing report of Gonsolin to Kendall Rogers of D1 Baseball:
"When we got here, we liked Anthony. He was athletic, he could run well, he had a good arm, he was strong, he just needed some time to develop," Valenzuela said. "He’s a guy that just continues to develop. He’s a hitter, and being a pitcher for him is a hobby right now. But we’re looking at him as a potential leadoff hitter or three-hole hitter, and we also want to close him in the spring.
"He’s the type of guy who can do something like that," he continued. "He’s just an overall very good player. He was a shortstop in high school, and can kind of do everything, and he’s got power on top of all of that. He’s a different guy."
