4. Tampa Bays Rays: Brendan McKay, Louisville 1B/LHP
McKay, who on Thursday was named Baseball America's College Player of the Year, has been in play for the overall top pick thanks to his two-way skills, which have earned him first-team All-America honors for three straight year—a trio of seasons that BA ranked among the top 10 by two-way players since 1999. For what it's worth, five of the six players from that list to reach the majors did so as pitchers, with Jason Jennnings winning NL Rookie of the Year honors as a starting pitcher and Sean Doolittle making an AL All-Star team as a reliever; the lone hitter, A.J. Reed, struggled in a 45-game stint with the Astros last year and is now back in Triple A.
As for McKay, some scouts consider the 6'2", 214 lb lefty swinger the best pure hitter in the draft class thanks to his smooth swing and all-fields approach. Others like his 89–93 mph fastball, plus curveball and average changeup and see someone with a quick pathway to being a number three starter, particularly given the expectation that he'll gain velocity once he focuses on pitching full time. He's upped his game on both sides of the ball this year, tapping into his raw power (he clubbed 17 homers after hitting 10 in his first two seasons) and adding another weapon to his arsenal, a cutter. With Louisville reaching the College World Series, McKay's pitching workload could lead to a post-draft shutdown, but that doesn't mean that route will be closed off come instructional league or 2018.
