Estrada has spent the past four years in Toronto, two of which were good and two of which were not so good. The worst, unfortunately for his free agency prospects, came this past season — the worst of his career — in which he posted an unsightly 5.64 ERA and a K/BB ratio of 103/50 in 143.1 innings. That explains the low-dollar affair. Estrada made $13 million last season on a one-year deal with the Jays.
Still, the A’s were desperate for starting pitching in the second half last season and still could use arms heading into 2019. For low money, it makes some sense for them to gamble on a bounce back season from the 35-year-old righty.
