Sleith led the RMU pitching staff in Florida by putting up dominating numbers against opposing batters. She started out the week with one of the best performances of her career as she twirled a three-hit shutout against Eastern Illinois. She tallied 14 strikeouts, just two off the school record, which was the highest figure by a Colonial in a regulation game since 2005. In throwing 64 of her 89 pitches for strikes, Sleith picked up her first shutout of 2013 and the sixth of her career despite having just one run of support for the game. Sleith tallied her second straight win the following day against Lehigh by allowing two runs in seven innings. The next day Sleith would come on in relief in both RMU contests and work out of difficult situations. Sleith went 3-1 on the week with two saves and registered a 1.37 ERA. She allowed opponents to hit just .160 while posting 42 strikeouts, against just five walks, in 30.2 innings pitched.
