Auburn redshirt junior right-hander Alex Petrovic was the Mets’ choice in the sixth round (181st pick). A big frame at 6-5 and 235 pounds, the 22-year-old had 92 strikeouts in 92⅔ innings across 17 starts that helped make him a high selection after going undrafted a year ago when eligible. He added about 3 mph of velocity, touching 96 mph while sitting 92-93 mph. He also has a good changeup to go along with a sweeper and a cutter. He battled arm inflammation in high school and when he stepped onto the Auburn campus, then had a stress fracture in his elbow that first spring and had surgery. The same injury cropped up the next year, but he chose a different recovery path and has been healthy since.
