Tonkin pitched 1.2 innings in Tuesday's victory over the Marlins, retiring each of the five batters he faced.
Although his ERA has risen to 3.10 after being in the realm of 2.00 for the first month and a half of the 2016 campaign, Tonkin has made strides to improve his game, particularly in terms of pitch control. After walking seven batters in his first 12 innings of action, Tonkin has walked only two in his last 17 frames. His strikeout rate has also improved from 2015's mark of 19 percent to 28 percent.
