Imanaga pitched into the seventh, improved to 4-0 through his first five starts for Chicago and headed off the hill with a 0.98 ERA. The lefty struck out seven and issued one walk, upping his ratio to 28 strikeouts against just three walks in 27 2/3 innings on the year.

As a result, Imanaga became the first Cubs starter to go at least 4-0 through the first five games of his career, and only the 37th pitcher to do so in AL/NL history. He is the first starter since 1945 (Boston’s Dave Ferriss) to go at least 4-0 with an ERA below 1.00 in his first five career games.
