Slania was drafted by the
San Francisco Giants in the fifth round, with the 162nd overall selection, of the
2013 Major League Baseball draft. He made his professional debut for the Low-A
Salem-Keizer Volcanoes, posting a 3.95 ERA over 12 games. Slania split the 2014 season between the Single-A
Augusta GreenJackets and Double-A
Richmond Flying Squirrels. In 53 appearances out of the
bullpen for the two affiliates, he compiled an aggregate 2-5 record and 3.47 ERA with 49 strikeouts and 12
saves over 70 innings. In 2015, Slania made 59 relief appearances for the High-A
San Jose Giants, logging a 4-5 record and 3.53 ERA with 90 strikeouts and 16 saves across innings pitched. Slania became a starting pitcher midway through the 2016 season after previously pitching in relief throughout his career and in college. In 34 appearances (16 starts) split between San Jose, Richmond, and the Triple-A
Sacramento River Cats, he registered a combined 11-8 record and 2.93 ERA with 111 strikeouts across innings pitched. On November 18, 2016, the Giants added Slania to their
40-man roster to protect him from the
Rule 5 draft. On June 28, 2017, following an injury to
Mark Melancon, Slania was promoted to the major leagues for the first time. He made his MLB debut on June 30, tossing a scoreless inning of relief against the
Pittsburgh Pirates, and was optioned down to Triple-A the following day. On November 20, Slania was removed from the 40-man roster and sent outright to Triple-A Sacramento. Slania spent the 2018 season with Double-A Richmond, posting a 1-3 record and 2.43 ERA with 69 strikeouts in innings pitched across 47 appearances. Slania was released by the Giants organization on March 18, 2019. ==References==
